I contacted Supbeam on the new K50 and X60. They should be shipping 11/20/13 and the K50 is $99 and the X60 is $299. Let's hope Vinh can get a deal and get them modded close to retail!
You are right, once a person has purchased the light they can have it modded if they want to, of course. What Vinh gave his word on, is that he will not talk about doing a run on these for awhile.
